I was wondering if it was possible to switch the logic board of the 13" Mid 2010 model with the 2009 model of the same size? I know the alignments are exactly the same on both models, but I am looking for a better graphics integrated graphics card, something better than the 9400m from Nvidia. I search iFixit but found nothing, has anyone here tried doing that and/or succeeded/failed? Any help would be appreciated!! Thanks in advance guys!
